FLIER FOR SPINNING MACHINES Filed Oct. 29, 1934 [I LY,

Patented Sept. 24, 1935 UNITED STATES PATENT OFFICE FLIER FOR SPINNING MACHINES Application October 29, 1934, Serial No. 750,463

18 Claims.

This invention relates to certain new and useful improvements in the fliers employed in connection with spinning machines and the like.

One of its objects is to provide a flier of this character having automatic braking or arrest- 3 of the brake-carrying element.

ing means which is designed to permit the normal, free running of the flier but which will positively arrest its turning at substantially the same time the bobbin is brought to rest.

A further object of the invention is the provision of a brake-equipped flier which is simple, compact and inexpensive in construction and wherein the brake element is so mounted as to be effectually protected against breakage and against interference with the threads and at the same time limited in its downward or brake-engaging position.

A still further object is the provision of an efficient flier wherein its several parts may be quickly assembled and interlocked as a unit.

Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawing: Figure 1 is a fragmentary front view of a portion of a spinning machine showing my improved flier positioned on the spindle. Figure 2 is an enlarged top plan view of the flier. Figure 3 is a bottom plan view thereof. Figure 4 is a fragmentary vertical section taken substantially in the plane of line 4-4, Figure 2. Figure 5 is a perspective view of the bearing sleeve and retaining washer. Figure 6 is a perspective view Figure 7 is a perspective view of the brake. Figure 8 is a similar view of the resilient brake-engaging element.

Similar characters of reference indicate corresponding parts throughout the several views.

This invention is applicable to spinning machines of any suitable and well known construction, I indicating the bobbin-spindle and II the take-01f bobbin mounted thereon. The thread or yarn from the bobbin extends upwardly through the eyes of the flier wires I2, I3 mounted on a holder or flier-body applied to the bobbin-spindle and thence upwardly through a guide or centering eye I4 to a take-up spool (not shown). The bobbin shown is of the type used with fliers of the eccentric type and has a recess I in its top containing an inverted cup-like member I 6 having an opening I! therein arranged eccentric to the axis of the bobbin-spindle.

The flier-body preferably consists of an attaching sleeve orbarrel I8 made of fiber or like material and adapted to befitted over the spindle I 9 above the bobbin. At its lower end this sleeve has aneccentrically-shaped flange I9 adapted to be passed through the cup-opening I'I during the application and removal of the flier -to and from the spindle and its flange is arranged to abut against the underside of the cup-like member I6 in the operative position of the parts. Spaced above the eccentric flange is a substantially circular flange 2| and disposed above the latter and fitted about the sleeve I8 is a base plate or spider 22 to which the flier wires I2, I3 are detachably connected, the base plate being firmly and securely anchored to the sleeve to produce a 5 practically unitary structure.

The base plate 22 is'provided centrally thereof with an opening 23 about which is an outwardly-facing annular bead or flange 24 spaced from the top side of said plate to provide an an- 0' nular groove 25 in which is disposed a rotatable locking ring 26. Stampedfrom the base plate near its opposite ends are wire-retaining loops 2'! which are adapted to receive the shanks of the flierwires I2, I3 in the manner shown in Figures 5 2, 3 and 4. At its diametrically opposite sides, the locking ring has vertically-offset flanges 28 which overlap the bent inner ends of the flier Wires in the locked position thereof, the vertical Webs of the flanges serving to deflect or spring 30' such bent ends of the wires laterally to hold them in their retaining loops 21. Secured by a pressed fit in the base plate opening 23 is a washer 29 which serves to anchor the base plate to the sleeve I3. I

Applied to the flier-body is a braking device which is adapted to frictionally contact with the adjoining portion of the bobbin II for arresting the rotation of the flier relative to the latterand preventing its over-running the same. In the preferred construction of the braking device shown in the drawing, the same consists of a brake element in the form of a wire bail or loop 38 hingedly suspended from a carrier plate or member 3| fitted about the sleeve l8 between its flange 2| and the base plate 22. The'inner or free ends of this brake element terminate in transverse hinge-pintles 32 detachably' fitted in upwardly-opening notches 33 formed in the carrier plate 3! and projecting outwardly from the opposing ends of. such pintles are arms 34 which are housed withinapocket 35 formed on said carrier plate, as shown in Figures 4 and .6. Interposed between this carrier plate and the base plate 22 about the sleeve I8 is a washer 36 having a resili- 55.

ent lip 31 overhanging the pocket 35 and bearing against the bail-arms 34 to constantly urge the bail 39 to swing downwardly into braking contact with the bobbin as well as yieldingly resist its upward swinging movement. These bail arms are deflected downwardly at a slight angle to the plane of the bail and abut against the bottom side of the pocket 35 to thereby limit the downward-swinging movement of the bail.

As shown in Figure 4, the pocket 35 projects downwardly below the plane of the carrier plate 3| and thus forms a shoulder 38 which abuts against a flat face 39 formed on the sleeve-flange ill to prevent relative turning of said plate on the sleeve i8. To prevent turning of the base plate 22 relative to the sleeve, its anchoring washer 29 has a depending prong 40 which extends through alining openings ll and 42 in the washer 36 and the bail-carrying plate 3!, respectively,

and which pierces or is driven into the sleeveflange 2i, as shown in Figure 4.

Applied to the top of the sleeve- I8 above the flier-wire bearing plate 22 is a fiber washer 43 which acts to hold the parts l8, 3! and 36 as a unit on the sleeve, the upper end of the latter having its outer edge rolled over said washer to prevent its vertical displacement.

During the rotation of the bobbin I I at its normal speed, the centrifugal force urges the braking element 38 upwardly against the resistance offered by the resilient lip 3'7 to a substantially horizontal position where it is clear and free of the bobbin and does not interfere with its normal operation. However, should the speed of the bobbin be lowered, as when stopping the machine, the braking element or bail will gradually be urged to swing downwardly by the spring lip 3'3 contacting the bail-arms 34, until, at a predetermined speed of the bobbin, the bail will contact gently with the top face of the bobbin and the resulting friction between the parts will cause the movement of the flier to be arrested with that of the bobbin, the friction effect being increased as the speed of the bobbin is lowered.
